HERE IS UR ANSWER
total surface area of cylinder = 2pie r ( r+ h)
1628cm^2 =2× 22/7 ×r (37)
1628/2 = 22/7 ×37r
(814× 7 )/22 = 37 r
259/37 = r
7 = radius
now = r+ h = 37
7 +h =37
h = 37- 7
h = 30
total surface area of cylinder = 2pie r ( r+ h)
1628cm^2 =2× 22/7 ×r (37)
1628/2 = 22/7 ×37r
(814× 7 )/22 = 37 r

7 +h =37
h = 37- 7
h = 30
